Geometry Shapes Playground Safety
Learners create a new playground design to present to elementary students during Playground safety week. They review basic geometry to use in observing and recording the equipment on a local playground. They research playground safety...
Curated OER
Exploring Secants: Products of Segments
Young scholars explore secants and circles. In this geometry lesson, students identify the properties of two and three dimensional shapes. They create arguments to prove the theorems are true.
Curated OER
Are you in Golden Shape
Students solve and verify the solution for unknown measures. In this geometry lesson, students identify the properties of circles. They use the arc, angle and segment relationship to find the missing measures.
Curated OER
Geometry Scavenger Hunt
Learners use the digital camera, identify geometric shapes (in nature as well as man-made), and gain a better understanding of geometric vocabulary. They search for and recognize geometric shapes in unusual settings
Curated OER
Castles
Students create a scale model to a castle using the dimensions they were given. They calculate the surface areas and volumes of each section of their castle.
